DEVICE FOR SECURING SHAFTS IN BEARINGS.

SPECIFICATION forming part of Letters Patent No. 387,445, dated August'7, 1888.

Application filed October 28, 1887. Serial No. 258.594.

To all whom it may concern..-

Be itknown that I, GEORGE W. PRoU'rY, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Devices for Securing Inking- Rollers and other Shaftsin-their Saddles or Bearings, of which the following, taken in con'nection with the accompanying drawings, is a specification.

My invention relates to devices for securing shafts in their bearings,and is particularly adapted to use in connection with the inking-rollersof printing-presses and their saddles.

The saddles of printing-press rollers are usually open bearings, theopen sides of said bearings being guarded against possible accidentalremoval of said rollers from their bearings by means of pins fitted toholes in the two arms of the forked saddlesand extending across the opensides of said bearings, which pins have to be removed every time it isdesired to remove or insert an inking-roller, and as said pins arenecessarily small and detached from any connection with the machine whenremoved they are very liable to get lost or mislaid, often causing greatloss of time in looking for them. To obviate this objection is theobject of my invention; and it consists in a fastening device composedof a wire fitted to a bearing extending longitudinally through the shortarm or fork of the saddle, and having its inner end bent at a rightangle to said bearing and extending across the opening of the saddle andits outer end bent into ascroll or other suitable curved form to adaptit to serve as a spring to hold said rightangled portion in position tobridge the opening in the saddle, and in the combination of such asecuring device with a saddle or open shaft-bearing having a recess ordetent formed in its outer end to receive said spring portion of thesecuring device and lock it in position.

Figure 1 of the drawings is an elevation of an inking-roller saddle, abearer-roll, a portion of an inkingroller, and a portion of thesaddle-rod with my invention applied to the Saddle. Fig. 2 is anelevation of the same (No model) parts, looking at right angles toFig. 1. Fig. 3 is a sectional elevation of the saddle, the cutting-planebeing on line a; 00 on Fig. 1; and Fig. 4 is apartial elevation ofthesaddle, looking in the opposite direction to Fig. 1.

In the drawings, A is the inking-roller; B,

the bearer-roll; G, the saddle or open-sided bearing, and D is thesaddle-rod.

The saddle G is of usual construction, except that the short arm athereof has a hole drilled longitudinally through the same to re ceivethe securing device E, and has formed in its outer end the detent-notchb, as shown in Fig. 4. The securing device consists of a wire passedthrough the hole in arm a, and having a portion, 6, of one end bent at aright angle to the portion in said hole and a portion of its oppositeend bent, preferably, into the form of a scroll, 6, though other Stylesof bend may be used which will permit said bent portion to engage withthe detentnotch b and be readily Sprung to remove it therefrom when itis desired to turn the securing device into the position shown in dottedlines in Fig. 2 for the .purpose of removing the roller or shaft fromthe saddle or placing it in position therein. By this construction theinking-roller or other shaft may be placed in position or removedwithout withdrawing the securing-pin and thereby renderingit liable tomisplacement or becoming lost, the securing device, on the contrary,always being in position to be readily operated and cannot becomelost ormislaid.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is

l. A saddle or open-sided bearing, in combination with a securing devicemounted permanently in an aperture in said saddle, and

vice E, consisting of a wire provided with t0 thisspeeification, in thepresenceoftwosubthe right-angled arm a at one end and the scribingwitnesses, on this 27th (lay of Octocurved portion e'at the other end,constructed her, A. D. 1887.
